1st off, just another +1 for mux for the service

But -0,02 for mux for taking 2% without warn!

I received the payment and didnt know what was wrong your post, mux. Obviously im joking here, you have to put your fees so you can have your earnings from this awesome job.
Now, a lot of things I would like to suggest have already been suggested or you have already implemented, but here are some important aspects:
- rating/feedback on rentals (done)
- some sort of msg system between leaser and renter
- some sort of publicity to bring some more renters maybe? I'm guessing that now there's a lot more leasers than renters.
- Possibility to allow "another hour" for some direct compensation between leaser and renter.
- Accept payment in other coins - this is a delicate aspect, but i'm thinking LTC is a must alongside BTC and probably a few others. The question would be how to sort it and also which coins to choose. Also some sort of FIAT payment option would bring in some more casual people with no crypto yet.
There are some more ideas I have in mind, but I guess these would have you coding for the next few days, would you accept them

Again, congrats on your project and good luck.
On a side note, just letting newcomers know that I have used this service as a leaser and everything went smoothly.
